“…Thus, if a BOT has been diagnosed with no invasive implants, after an intensive patient consultation, the following procedure can be chosen: a detailed exploration of the abdomen, a peritoneal lavage, peritoneal biopsies from all regions of the abdomen, a unilateral salpingo-oophorectomy (USO), an omentectomy and in addition for mucinous BOT the appendectomy (Schmalfeldt and Pfisterer, 2007). According to current studies evaluating conservative surgery in this group, high conception rates were achieved after a simple ovarian cystectomy (Longacre et al, 2005;Marcickiewicz and Brannstrom, 2006;Tinelli et al, 2006;Yinon et al, 2007), but the high risk of local recurrence of up to 75% still limited the routine implementation (Suh-Burgmann, 2006). Results of cystectomy for BOT suggest a higher risk of intraoperative cyst rupture and of recurrence when compared with USO or BSO (Poncelet et al, 2006;Yokoyama et al, 2006).…”
